Phone and Telephony Network Overview

Cisco Unified IP Phones enable you to communicate by using voice over a data network. To provide this
capability, the IP phones depend upon and interact with several other key Cisco Unified IP Telephony and
network components, including Cisco Unified Communications Manager, DNS and DHCP servers, TFTP
servers, media resources, Cisco PoE, and others.
This chapter focuses on the interactions between the Cisco Unified IP Phone 7975G, 7971G-GE, 7970G,
7965G, and 7945G and Cisco Unified Communications Manager, DNS and DHCP servers, TFTP servers,
and switches. It also describes options for powering phones.

device, such as a Cisco Catalyst switch. You must also register the Cisco Unified IP Phone with a
Cisco Unified Communications Manager system before the phone can send and receive calls.
